Why listen to your music via inferior converters on your laptop when you can use Shure's high-quality KSE1500 via USB? If you love audio, you can't go wrong with a maximum quality of 24 bits at 96 kHz, a rich frequency range of 10 - 50 kHz and a 4-band equalizer.

This ingenious little device is a sort of new DAC for your laptop (that is usually supplied with inferior 'budget' components), for example. The result is excellent audio sent to your headphones via USB.
